Please discuss regenerative catalytic combustion and flow direction reversal devices for the purification of organic waste gases

Thread Content

Catalytic purification devices generally include conventional devices, Regenerative Catalytic O*dizers (RCO), and RFR, among others. In the 1960s or earlier, the above two types of industrial waste gas incineration devices were already in industrial use abroad, such as at Osaka Oxygen Industry Company and the French company Rhône-Poulenc. 3M uses RCO to treat exhaust gases containing butane and other solvents ； General Motors uses RCO to treat waste gas containing styrene ； Philips Electronics uses RCO to treat exhaust gases containing propylene, toluene, butylene, etc. Most studies on RFR and its models focus on the catalytic combustion of methane and similar substances; there are also studies on the deactivation of catalysts in the use of RFR technology. Matros, one of the main pioneers in flow-switching catalytic reaction technology, provided a thorough overview of RFR as well as the dynamic operation of reactors. He discussed the characteristics of catalytic combustion for VOCs through flow switching and proposed various methods for regulating the properties of heat waves. Salomons et al. studied the heat wave characteristics of catalytic combustion of methane at low concentrations and explored the stability of the reaction systems. Davide et al. treated VOCs using both conventional reactor networks and flow-switching reactors, and compared the stability of the reaction systems in each case. Application examples include VOC emissions from industries such as chemical plants and plastic production for cables. Please discuss, provide more information, and learn from one another. Thank you.
